Application filed January 29, 1914. serial Ito. $15,182.

To all whom it may concern Be it known that I, ALFRED A. DENNIS, a citizen of the United States, residing at Grand Rapids, Michi an, have invented ertain new and useful mprovements in ue- Distributors for Veneer-Taping Machines or Machines for Similar Purposes, of which the following is a specification.

This invention relates to improvements in glue distributors for veneer taping machlnes or machines for similar purposes.

The objects of this invention are: First, to provide an im roved device of this sort which is particu arly adapted for use in combination with a veneer taping machine. Second, to provide in a device of this sort means whereby the glue covered strip is delivered to the taping machine of a proper consistency.

Further objects, and ob ects relating to with the glue details and economies of structure and op-- a longitudinal sectional view on tl'ie irregu-v lar line 22 of Fig. I. Fig. III is a sectional view on the line 3-3 of Fig. 11'. Fig. IV is a sectional view on the line 44 of Fig. III, showing in detail the supporting pad. Fig. V is a view, partly in section showing a modified form of pad.

In the drawing similar reference characters refer to similar parts throughout the several views and the sectional views are taken looking-in the direction of the little arrows at the ends of the section lines.

Considering the numbered parts of. the drawing. 2 is the top frame of a veneer taping machine to which my glue distributing device is attached. The casing 3 is supported on a bracket 4 which is secured to the frame 2 by means of the bolts 5 and to which the tank is fastened by means of the hinge 6. Within the outer casing 3 of the tank is provided a glue reservoir 7 which is shaped like an inverted pyramid. This reservoir has a filling opening in its upper end WhlCh is closed by means of the screw cap 8. The apex of the inverted pyramid extends beneath the casing and is rovided with a slot-l ke opening .9 throug which the glue 1S1 dlschar ed. The space between thelinverted pyramid and the outer walls of easing 3 serves as a water jacket in which hot water may be placed to keep the glue in a melted condition.

10 1s a plate which is pivoted on the rod 11, secure in brackets depending from the bottom of the glue tank. To the under side of this plate 10 is secured the rod 12 which carries the weight 13. This weight is located near the outer end of the rod 12 and on the inner end of the plate 10 is provided the flanged holder 15 cured t .e supporting pad 14 of felt or similar material saturated with water so as to be moist. The action of the weight 13 is to keep the pad 14 normally in contact with the outlet of the glue reservoir.

To the upper side of the tank is secured a rod 17 which extends upwardly and rearwardly and at. its outer end is bent laterally. Upon the outer end of said rod is secured the reel of paper to be coated, and 16 is a strip of paper extending downwardly from said reel through suitable opening in the bracket 4, between the slot 9 in said glue reservoir and the pad 1% and thence over the roller 18 which is supported by the yoke 19 adjustably secured to the bottom of .the tank. The yoke 19 has the rearwardly turned ends 22 which .pass through clips 23 secured to the bottom of the tank. One of the clips carries a set-screw 24 engaging the end 22 to hold the yoke in adjusted position. By means of this arrangement, the

. distance between the glue discharging openregulated. This through which the water jacket may be filled with hot water. This may be drained out from the jacket through the pet cook 21.

t As I have already indicated, the paper to be glued is fed down .from the reel through opening 9. The glue is discharged through the opening and covers the upper surface of the paper and the pad 14 serves to support the paper at this point. From the pad the paper is carried over roller 18 and thence downwardly to the veneermg machine where it is delivered with the glued side down.

J is adapted to use in any sort of work in, which the use of gummed tape is required.

In Fig. V I have shown a modification in which the plate 10 is provided with upstanding ears 25 in which there is journaled the rod or pin 26 carrying a felt roller 27 which is adapted to normally engage the discharging slot in the bottom of the glue tank. As will readily be seen this felt roller may be used in place of the rectangular felt pad 14 shown in Fig..III.

I am aware that the structure which I have here shown is susceptible of considerable variation without departing from the spirit of my invention and I, therefore, do not wish to be restricted to it. I have shown this device used in connection with a veneer taping machine, but it will be evident that it However, this particular embodiment is to be preferred and, I, therefore, desire to claim the same specifically as well as broadly, as indicated by the appended claims.

I have shown the device furnished with a water jacket forwarming and melting the glue. It will be evident that any other suitable device might be used for this purpose, such as an electric heating device for example.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent. is:

'1. In a device of the class described, the combination of a glue tank, a'water jacket surrounding the same, a discharging 'slot at the bottom of said tank,- brackets secured to said tank. a plate pivoted on said brackets, a pad of felt secured to said plate in alinement with said discharging slot, a rearwardly extending rod secured to said plate, a weight on the rear end of said rod, adapted to keep the pad normally in engagement with the bottom of the tank, a bracket adjustably secured to the bottom of the water jacket, a

rearwardly extending rod secured to said V plate, a weight on the rear end of said rod,

adapted to keep the pad normally in engagement with the bottom of the tank, a bracket adjustably supported, a roller supported on said adjustable bracket in alinement with said .pad ,all coacting substantially as described fOIJghB purpose specified.

3. In adevice of theclass described, the, combinationwlth' asupporting bracket, of a glue tank hingedly'carried thereby, a narrow discharging slot at the bottom of said tank, a plate pivotally securedto said tank, a pad of felt carried by said plate inalinement, with said slot, means holdingsaid pad normally in engagement withthe bottom of said tank, a bracket adjustably secured to the bottom of said tank, and a roller carried thereby, all coacting substantially as-described for the purpose specified.

4. In'a device of theclass described, the" combination of a glue tank having a discharge slot in the bottoni j lthereof. and a roller adiustably supported whereby the distance between said roller and said slot can be varied to time the solidifying of said glue, all coacting substantially as described and for the purpose specified. I

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
